Separate debuggee/tracee build from product build

[hoyosjs]

• New Debuggees.proj - moves debuggee and tracee projects out of the main build traversal into a dedicated project built with the test SDK instead of the global.json Arcade SDK.
• Runtime installation refactored - runtimes are now installed via dirs/test.proj instead of from the main build script; eng/installruntimes.* scripts and InstallRuntimes.proj updated accordingly.
• Pipeline improvements (build.yml) - reorders post-test steps (publish test results first), replaces CopyFiles@2 with a pwsh move + tar.gz step to avoid ENOSPC failures on mac hosts.
• Test disables with open issues - disables DumpStack/EEStack on macOS and dumpobj verification on Alpine for known platform-specific failures; updates several script regexes (DumpGen, GCTests, Overflow, StackTests, WebApp) for compatibility.
• Minor code changes - call out issues in DumpAsync for runtime-async, event pipe log/trace test improvements, test helper adjustments for the new build step model, and some react to new payload shapes in newer versions of Logging EventSources.

Pull request overview

This PR restructures the build/test flow to decouple debuggee/tracee builds (and test runtime installation) from the main product build, while moving test infrastructure forward to include .NET 11 and updating tests/pipelines accordingly.

Changes:

• Move test runtime installation into src/tests/dirs.proj (and remove the unit-test install hook from src/Directory.Build.targets / build scripts).
• Build debuggee/tracee projects via a new src/tests/Debuggees.proj using the installed test SDK (with cross-arch support via a host-arch SDK install).
• Update tests/scripts and pipeline behavior for new runtime behavior (.NET 11 async/runtime-async, updated DiagnosticSource behavior, improved failure artifact collection).

eng/pipelines/build.yml:75

• isCodeQLRun was removed from this template, but diagnostics-codeql.yml still passes isCodeQLRun: true when referencing /eng/pipelines/build.yml. This will break the CodeQL pipeline due to an unexpected parameter. Either reintroduce the parameter (even if it becomes a no-op) or update the callers in the same PR.

nit: I think the previous invocation format was easier to read and understand

cDAC pipeline: https://dev.azure.com/dnceng-public/public/_build/results?buildId=1416195&view=results

[hoyosjs]

This shows an E_NOIMPL from the cDAC in GetGCHeapData?

This shows an E_NOIMPL from the cDAC in GetGCHeapData?

We can look into it in a follow up. This looks good to go!

[hoyosjs]

I am OK if @max-charlamb and @rcj1 are ok with.

[max-charlamb]

Good with me. Can investigate that cDAC failure after it's merged
